A body found Thursday buried beneath a concrete slab at a northwest Harris County home is that of a man missing for nearly two years.

Texas Equusearch said in a release that its members worked with the Harris County Sheriff's Department to unearth a "very deep grave" in the 12300 block of Chute Forest Drive.

The Harris County Institute of Forensic Sciences identified the body as that of Michael Watley, who disappeared in February 2012.

Sheriff's Department spokesman Thomas Gilliland said Saturday morning the office homicide investigators had not released any information on the incident.

Watley was last seen Feb. 14, 2012, in the area around Angie Drive, about six miles from the house where his body was found. Volunteers looked for him for days after his disappearance.

A man listed as living at the home where the body was located, Josue Santuario, was charged Thursday with tampering with evidence related to the body's discovery. Santuario remains in custody on a $15,000 bond related to two drug possession counts he also faces from the Thursday arrest.
